Abstract (en)
[origin: EP2813337A1] Provided is a tire mold capable of suppressing the occurrence of bare defects in the bead portion and also of manufacturing a pneumatic tire having excellent adhesion to the rim even if the tire has a downsized bead filler, and also provided is a pneumatic tire with a downsized bead filler having fewer occurrences of bare defects in the bead portion and excellent adhesion to the rim. The tire mold has a bead portion molding surface for molding the bead portion of the tire, the bead portion molding surface having a ridge molding part including a recessed groove extending in the mold radial direction, the ridge molding part being formed in a flange contact portion molding region for molding a rim-flange contact portion of the tire. In the pneumatic tire, the bead filler has the tire radial direction outer end positioned more inward in the tire radial direction relative to the rim line position, and a ridge forming portion including a ridge extending in the tire radial direction is formed on the outer surface of the bead portion, the ridge forming portion being positioned in the rim flange contact portion.
